Puts every word from a file into a new line

Simply translates whitespace to newlines. Could be enhanced to compress out extra newlines, but that might be better handled in the next tool down the pipe, with eg uniq(1).

Alternative size (human readable) of directories (biggest last)

Display a cool clock on your terminal

This command displays a clock on your terminal which updates the time every second. Press Ctrl-C to exit.

A couple of variants:

A little bit bigger text:

watch -t -n1 "date +%T|figlet -f big"

You can try other figlet fonts, too.

Big sideways characters:

watch -n 1 -t '/usr/games/banner -w 30 $(date +%M:%S)'

This requires a particular version of banner and a 40-line terminal or you can adjust the width ("30" here).

Expand shell variables in sed scripts

With this command you can use shell variables inside sed scripts.

This is useful if the script MUST remain in an external file, otherwise you can simply use an inline -e argument to sed.

Working random fact generator

This is a working version, though probably clumsy, of the script submitted by felix001. This works on ubuntu and CygWin. This would be great as a bash function, defined in .bashrc. Additionally it would work as a script put in the path.

ls -hog

ls -hog --> a more compact ls -l

I often deal with long file names and the 'ls -l' command leaves very little room for file names. An alternative is to use the -h -o and -g flags (or together, -hog).

* The -h flag produces human-readable file size (e.g. 91K instead of 92728)

* The -o suppresses the owner column

* The -g suppresses the group column

Since I use to alias ll='ls -l', I now do alias ll='ls -hog'
